Fan assembly
First Claim
1. A nozzle for a fan assembly, the nozzle comprising:
- at least one air inlet;
a plurality of air outlets, the nozzle having a front end and a rear end opposite the front end the air outlets being arranged to emit air towards the front end of the nozzle;
an annular casing comprising an annular inner wall defining a bore through which air from outside the nozzle is drawn by air emitted from the air outlets and an outer wall extending about the inner wall, the annular casing comprising an air passage for conveying air to the air outlets, the air passage comprising an inlet section located between the inner wall and the outer wall and extending about the bore of the nozzle, and a plurality of outlet sections each extending across the bore for conveying air to a respective air outlet, the inlet section of the air passage being connected to each end of each of the outlet sections; and
an electrostatic precipitator located between the air outlets and the rear end of the nozzle.

Abstract
A nozzle for a fan assembly includes an air inlet, a plurality of air outlets, and an annular casing having an annular inner wall defining a bore through which air from outside the nozzle is drawn by air emitted from the air outlets and an outer wall extending about the inner wall. The annular casing includes an air passage for conveying air to the air outlets. The air passage has an inlet section located between the inner wall and the outer wall and extending about the bore of the nozzle, and a plurality of outlet sections each extending across the bore for conveying air to a respective air outlet. To achieve an even air pressure at each end of each of the outlet sections, the inlet section of the air passage is arranged to convey air to each end of each of the outlet sections.
